We've just executed the INSTLIB job in CICAT because we're upgrading to z/OS 1.12.

We only use Omegamon CICS and Omegamon z/OS.
We are no expert in omegamon enviroment. It's the first time that we must upgrade Omegamon in our systems. We've applied ptfs and upgrade the version through ICAT menu, but not the release. All the coexistence ptfs for z/OS 1.12 are installed.
We have only a test system in a test sysplex

We have several doubts:

- We're reading the OMEGAMON XE and Tivoli Management Services on z/OS Version 6.2.2 Fix Pack 2 Upgrade Guide. In the chapter 2, upgrade paths, path b, step 4 says: "If you plan to run the hub monitoring server on a z/OS
system,...". We suppose that our hub monitoring server is the TIVOLI ENTERPRISE MONITORING SERVER. Could be?.
- If this question is true, the technote High-Availability Hub Tivoli Enterprise TEMS on z/OS tells the instructions for configure the hub to make it moveable. We have only one system. Must we applied this configuration in the hub?
- If we don't execute the step above we must continue with the Chapter 5. Batch upgrade scenario. The first paragrah says: "Upgrading most OMEGAMON XE monitoring agents from V4.1.0 to V4.2.0 does not require full product
reconfiguration". We don't need upgrade anything in our actual release V4R1?
